A Kiss of Shadows introduced Meredith Gentry, a princess of the dark court of the Unseelie, who had been hiding from her vindictive aunt, the Queen, and working as a detective in Los Angeles. The fey are in the United States by treaty but are not supposed to use dark arts on humans. Their extra senses may be used to help the forces of law and order however.

In A Caress of Twilight , Merry is invited to the home of a movie star, who has been banished from the Seelie court by the king. Maeve Reed 's human husband is dying and she wants Merry's help in conceiving a child by him. But before Merry and her handsome bodyguards can help, they must assist human police in finding the being, the Nameless, created by both courts of Faerie, that of light and that of darkness, which is killing humans en masse trying to return itself to a corporeal state. Meanwhile, Merry is trying her best to conceive a child so that she, and not her evil cousin, Cor, son of Queen Andais, will become the next ruler of the Unseelie Court. She is also trying to avoid King Taranis of the Seelie Court.

This is definitely not for the faint of heart or narrow of mind. Hamilton updates elements of Celtic mythology in a successful blend of fantasy and horror, with a just a touch of mystery. In her efforts to conceive a child before her cousin does, Princess Meredith sleeps with one or two of her bodyguards nightly. A goblin stays nearby at almost all times, and a tiny member of the demi-fey also joins her entourage. There are some extremely funny bits as well as some really really horribly gory ones. Don't expect a fine mystery but do expect a fast paced story. I eagerly wait for the next foray into the complicated politics of the faery world.
